I would like to customize my pages 404 and 401.
So I used this:
server.errorfile-prefix = "/var/www/errors/status-"
The file "errors" contains:
HTML pages are displayed normally but not the attachments (.js or .png)...
mimetype.assign is correct, and owner directories are the same that server.username.
why html files are displayed and not others ?
Ok. I found a solution with Data URI scheme (http://en.wikipedia.org/wiki/Data_URI_scheme)
